The colors of plants and animals can be achieved by different interactions of light with matter. [10][11][12][13][14][15][16][17] Animals or plants use the biological system colors as warning, for camouflage, or for signaling. Coloration can be generated by the selective absorption of light from the visible range of the spectrum by using pigments (pigmentary colors), which are absorbing subsets of the visible spectrum and transmitting and reflecting the other parts of the visible light. Therefore, the tissue occurs in the color of the wavelength of the reflected radiation. This is used for example by flowers of plants as a signal, because they have to stand out against the background of the vegetation in order to attract pollinating insects. Therefore, they appear in bright colors by reflecting certain wavelengths of visible light, which are then perceivable for the pollinating insects as well as for humans. [10][11][12][13] However, light-matter interaction with respect to absorption is of general importance, but will not be further discussed in this review. On the other hand, coloration can be created by coherent or incoherent scattering of light on highly structured and unstructured tissues (structural colors) in the range of the wavelength of incident light. Here, different wavelengths of light are selectively reflected from a structure and the remaining wavelengths can then be transmitted or absorbed. [10][11][12][13][14][15] These biological photonic sub-micrometer structures yield a distinct coloration through the creation of a refractive index contrast between the used materials. This is an interesting fact, because natural systems cannot be built on high-refractive index inorganic materials, which are commonly used in contemporary technology. Instead, nature makes use of biopolymers such as keratin, chitin, collagen, and cellulose. However, all of these biopolymers exhibit a refractive index around ≈1.5. In order to be able to create bright structural colors, a high refractive index contrast is required. Therefore, nature is using air voids to create the necessary refractive index contrast (Δn ≈ 0.5). Alternatively, nature can also use melanin with a refractive index of about 2 and keratin in mixed composites or by using anhydrous guanine with a refractive index of 1.83, whose crystal arrangements are responsible for the metallic luster of many fish. [15,16] Pigmentary color as well as structural color can also occur in combination (combined colors). All of these aspects can also be separated in iridescent or noniridescent colors. [10,15] Birds, like the Panama Amazon parrot (Amazona ochrocephala panamensis) or the kingfisher (Alcedo atthis) are using different combinations of pigments and sub-micrometer structured components.Cellulose is one of the most abundant biopolymers on earth. It is a sustainable and renewable raw material with many beneficial properties. Due to its availability, nontoxicity, environmental friendliness, biocompatibility, and biodegradability, cellulose is one of the world's most ...

“…Surprisingly, it has not been broadly explored for fiber optics, [ 41 ] even though various cellulose derivatives and nanocelluloses have been widely studied for several other photonic applications. [ 42–54 ] Among a few examples, cellulose‐derived optical fibers have been reported based on hydroxypropyl cellulose (core)‐cellulose butyrate (cladding) fibers and cellulose acetate‐coated regenerated cellulose fibers. [ 55,56 ] Their preparation still involves high‐temperature treatments and ionic liquids.…”

Because of their lightweight structure, flexibility, and immunity to electromagnetic interference, polymer optical fibers (POFs) are used in numerous short‐distance applications. Notably, the incorporation of luminescent nanomaterials in POFs offers optical amplification and sensing for advanced nanophotonics. However, conventional POFs suffer from nonsustainable components and processes. Furthermore, the traditionally used luminescent nanomaterials undergo photobleaching, oxidation, and they can be cytotoxic. Therefore, biopolymer‐based optical fibers containing nontoxic luminescent nanomaterials are needed, with efficient and environmentally acceptable extrusion methods. Here, such an approach for fibers wet‐spun from aqueous methylcellulose (MC) dispersions under ambient conditions is demonstrated. Further, the addition of either luminescent gold nanoclusters, rod‐like cellulose nanocrystals or gold nanocluster‐cellulose nanocrystal hybrids into the MC matrix furnishes strong and ductile composite fibers. Using cutback attenuation measurement, it is shown that the resulting fibers can act as short‐distance optical fibers with a propagation loss as low as 1.47 dB cm−1. The optical performance is on par with or even better than some of the previously reported biopolymeric optical fibers. The combination of excellent mechanical properties (Young's modulus and maximum strain values up to 8.4 GPa and 52%, respectively), low attenuation coefficient, and high photostability makes the MC‐based composite fibers excellent candidates for multifunctional optical fibers and sensors.

“…The calibration graph of fluorescence intensity versus nitrite concentration was linear in the range of 2.0 × 10 −4 –5.0 × 10 −3 g/ml. With high sensitivity, satisfactory nitrite sensing in real samples was demonstrated [ 52 ]. Another MOPF modified with eosin-cellulose acetate (CA) was developed by using a liquid-phase coating for gaseous ammonia fluorescence sensing.…”

With the growing importance of optical techniques in medical diagnosis and treatment, there exists a pressing need to develop and optimize materials platform for biophotonic applications. Particularly, the design of biocompatible and biodegradable materials with desired optical, mechanical, chemical, and biological properties is required to enable clinically relevant biophotonic devices for translating in vitro optical techniques into in situ and in vivo use. This technological trend propels the development of natural and synthetic polymeric biomaterials to replace traditional brittle, nondegradable silica glass based optical materials. In this review, we present an overview of the advances in polymeric optical material development, optical device design and fabrication techniques, and the accompanying applications to imaging, sensing and phototherapy.
